- Description: This dissertation defends an account of oppression and supports a specific means of engaging with oppression cross-culturally. The project examines whether it is defensible to interfere in other cultures at all. Both the cultural relativist and the neo-imperialist approaches are argued to be an inadequate response to the question of whether it is defensible to interfere in other cultures, as both these approaches neglect the autonomy of the agents concerned. This project has two related goals. It first advances an answer to the question ‘what is oppression?’ An account of oppression is developed which will enable oppression to be identified cross-culturally. In order to start constructing an approach which will be adequate to respond to the question of interference, it is necessary to consider a means of identifying oppression crossculturally. The second objective is to examine the possibility of non-imperialistic and nonpaternalistic cross-cultural liberation projects. The first aim (advancing an account of oppression), is executed through arguing for an ethical framework which will be helpful in this context, and arguing for an account of oppression derived from this framework. The second aim (examining the possibility of non-imperialistic and non-paternalistic liberation), is carried out in two parts. The first part responds to two standard objections from cultural relativism, which would accuse a universal account such as mine of imperialism and paternalism. The first objection claims that a universalist account neglects historical and cultural difference, while the second objection claims that it neglects autonomy. In responding to these objections, it is noted that while my responses prove, theoretically, that a universal account of oppression need not lead to imperialism or paternalism, there is a danger that the account could become imperialistic and paternalistic in its application. With the intention of dealing with this problem, I advance a methodology of cross-cultural understanding which would reduce the likelihood of imperialism and paternalism in liberation projects. This notion of cross-cultural understanding is the most important contribution of this project. The objective is not to give practical judgments on when a specific liberation project is in fact paternalistic or imperialistic, but rather to propose guidelines which would need to be applied to each particular instance.

- Description: The arts in many countries, but particularly in developing ones, are coming under increasing financial pressure and finding it difficult to justify the increases in government funding needed to maintain and grow the cultural sector. The trend in cultural economics, as well as in other areas, appears to be towards including qualitative valuations, as well as the more traditional quantitative ones. This thesis argues that the value of cultural events should include long term historical qualitative analysis, financial or economic impact and a valuation of the positive externalities provided by cultural events and that any one of these should only be regarded as a partial analysis. Four methods of valuing the arts using the South African National Arts Festival (NAF) as an example are demonstrated. Firstly, a qualitative historical analysis of the role of the NAF in South Africa’s transformation process from Apartheid to the democratic New South Africa is examined, using theories of cultural capital as a theoretical basis. It is argued that the value of cultural events needs to take into account long-term influences especially in countries undergoing political and social transformation. The second valuation method applied is the traditional economic impact study. Four economic impact studies conducted on the NAF are discussed and methodologies compared. It is concluded that, despite the skepticism of many cultural economists, the method can provide a useful partial valuation and may also be used for effective lobbying for government support of the arts. Chapter four discusses willingness to pay studies conducted at the NAF in 2000 and 2003 (as well as a pilot study conducted at the Klein Karoo Nationale Kunstefees). It is found that lower income and education groups do benefit from the positive externalities provided by the Festival and that this is reflected in their willingness to pay to support it. It is also argued that such contingent valuation studies can provide a reasonably reliable valuation of Festival externalities, but that they may be partly capturing current or future expected financial gains as well. Finally, the relatively new choice experiment methodology (also called conjoint analysis) is demonstrated on visitors to the NAF. The great advantage of this method in valuing cultural events is that it provides part-worths of various Festival attributes for different demographic groups. This enables organizes to structure the programme in such a way as to attract previously excluded groups and to conduct a cost-benefit analysis for each part of the Festival.

- Description: The South African ostrich industry is presently characterised by a drastic decline in the slaughter price of slaughter birds, due to the drop in the price of meat as well as leather. As a result, the economic viability of ostrich farming is severely hampered by these developments, and many generally accepted industry practices have to be reviewed. Among the practices under review is the possibility of slaughtering ostriches at an earlier age than the traditional slaughter age of 12 - 14 months, in order to minimise feed costs and the incidence of damage to the skin. However, little information is available on the effect of the slaughter age on the yield and quality of the economically important end-products. The effect of slaughter age on production and the economic viability of a commercially intensive ostrich production system was consequently evaluated in a completely randomised experimental design involving two batches (n= 81 and n= 94) of ostriches. The experiments took place at Kromme Rhee experimental farm of the Elsenburg Research Centre near Stellenbosch. The birds were subject to experimental treatment at the age of 4 months (n= 81, from May 2004 to March 2005) and 6 months (n= 94, from August 2004 to August 2005) respectively. The ostriches were randomly divided into 10 groups of between 16 and 20 birds per group. Standard production practices, as applied in an intensive ostrich production unit, were implemented. Clean drinking water and self-mixed grower diet (min 15 percent crude protein, 0.68 percent lysine and 11.4 MJ ME per kg feed) and finisher diet (min 14 percent crude protein, 0.55 percent lysine and 9.8 MJ ME per kg feed) were provided ad libitum to the birds. Birds were slaughtered at the ages of 8.5, 10.5, 12.5, 14.5, and 16.5 months respectively. Data on feed intake and yields of cold carcass, crust skin size, skin grade and total feathers was recorded for birds slaughtered at the respective ages. Data was analysed according to the analysis of variances. Values for meat yield, skin size yield and feed intake were predicted by regression analysis based on experimental values. Industry figures and norms were used as proxy for other production inputs and costs. A gross margin type analysis was performed to evaluate the effect of different slaughter ages on the profitability of each production system. There was a positive correlation between age and feed intake (r2= 0.40), slaughter weight (r2= 0.97), cold carcass yield (r2= 0.48), skin surface area (r2= 0.39), skin grade (r2= 0.19) and total yield of feathers (r2= 0.29). The dry skin grade showed deterioration as slaughter age was prolonged. Highly significant differences (P< 0.01) in slaughter weight, cold carcass yield, skin surface area, dry skin grade and total feathers were detected at the different slaughter ages. There were no significant differences (P> 0.05) with respect to gender for slaughter weight, skin surface area and dry skin grade within the different age groups. Males had significantly higher (P< 0.05) cold carcass yield and total feather yield than their female counterparts. From this study it can be concluded that an increase in slaughter age significantly increases feed intake, slaughter weight, cold carcass yield, and skin surface area. It is also clear that an increase in slaughter age can be detrimental to dry skin grade. The relative income contribution of the three main products (skin: meat: feathers) occurred in a ratio of 47:53:0, 52:47:1, 47:50:3, 44:51:5, 39:56:5 at the respective slaughter ages. Total income revealed an increase of 26 percent from 8.5 to 10.5 months slaughtering, an increase of 4 percent between 10.5 and 12.5 months, and an increase of 11 percent between 12.5 and 14.5 months. The income dropped by 0.3 percent between 14.5 and 16.5 months slaughtering. Total costs increased with slaughter age, particularly feed costs which showed an increase (at a decreasing rate) between the different slaughter ages. The margin above specified cost per bird was the highest for birds slaughtered at the age of 10.5 months. The margin above cost showed a steady decline as birds were slaughtered at higher ages. Slaughtering at 16.5 months revealed a negative margin. To compare the effect of differences in time span on different slaughter age regimes, margin above costs for each system over 5 years were discounted to a present value. In this study, with current feed costs and income from end products, slaughtering at 10.5 months revealed the highest present value for the margin above cost. Furthermore, slaughtering at 16.5 months revealed a negative present value on the margin above cost after 5 years. Financial viability calculations are relevant and valid for data obtained in this case study. Financial viability is however case-specific and may vary between producers, depending on their individual management practices, production systems and cost structures. Results from this study may be of significant value to managerial decision-making in the ostrich industry.

- Description: Water hyacinth, Eichhornia crassipes (Martius) Solms-Laubach (Pontederiaceae), forms thick mats that affect water resource utilisation, but little is known about its impacts on biodiversity in aquatic ecosystems. The benthic invertebrate community and algal biomass were sampled under water hyacinth mats and in water hyacinth-free water over a 13-month period, using artificial substrates in New Year's Dam, Eastern Cape Province, South Africa. The number of families per substrate (U = 796.5, P 0.001), number of individuals per substrate (U = 620.5, P 0.001), Shannon-Weiner Diversity Index (U = 1 038, P 0.001), Margalef's Richness index (U = 1 136, P 0.002), Pielou's Evenness Index (U = 1 230, P 0.001) and chlorophyll a (U = 678, P 0.01) were all significantly lower under water hyacinth mats than in water hyacinth-free zones. Similarly, multivariate analyses showed more diversity in invertebrate communities in open water than under water hyacinth. Thus, the control of water hyacinth is important, in order to prevent both ecological and economic impacts of biodiversity loss.

- Description: Arbor Day, or Week, is a well-established greening initiative worldwide, focusing on tree planting and the benefits thereof. Frequently most effort is targeted at institutions such as schools and community groups. Yet there has been limited assessment of the success of Arbor Day, or Week, activities both at the schools, or the wider dissemination in neighbouring communities and suburbs. The objective of this study was to determine the influence of school-based Arbor Week activities on learners’ home-based practices regarding tree planting and urban forestry. Learners from three schools in Grahamstown, South Africa, with good Arbor Week participation, were assessed on their tree planting knowledge. The learners’ parents were also interviewed to determine whether the information obtained by the learners at school was taken home. A control group consisting of people with no children or very young children was also assessed. This study found that Arbor Week activities were, for the most part, successfully taught in the case study schools, and most of the learners stated that their knowledge of trees and their benefits came from their school activities. However, many learners could not remember the activities in which their schools partook the previous year. Whilst most learners were aware of the importance of trees, few had encouraged tree planting at home. However, over one-fifth of adults claimed that their knowledge of the benefits of trees was as a consequence of Arbor Day activities when they were young. Numerous constraints to tree planting were provided by learners and both the adult groups, the two most frequent being limited space and falling leaves making their yards untidy. External organisations should become more actively involved and provide much needed support systems if greening initiatives are to reach the wider community.

However, over one-fifth of adults claimed that their knowledge of the benefits of trees was as a consequence of Arbor Day activities when they were young. Numerous constraints to tree planting were provided by learners and both the adult groups, the two most frequent being limited space and falling leaves making their yards untidy. External organisations should become more actively involved and provide much needed support systems if greening initiatives are to reach the wider community.

- Description: Concussion is a common form of brain injury, especially amongst sports players of all age groups. ImPACT is a valid and reliable measure of a variety of cognitive functions commonly affected by such injuries, which allows for objective return-to-play decision making (Iverson, Lovell, & Collins, 2003). However, studies show that the transfer of such tests from one ethnic group to another without appropriate standardization is highly problematic (Ardila, 1995). Thus, the relative absence of South African normative data for the ImPACT 3.0 programme is an issue for concern. Consequently, this study aimed to establish norms for semi-rural Xhosa-speaking schoolboys with an advantaged education (ages 14, 16 and 18) for the ImPACT 3.0 programme as administered in English. Administrative and linguistic difficulties that were experienced by individuals during completion of the battery were also identified. Finally, the study included a comparison of the percentile scores of this sample to the USA norms for boys of a similar age group. Subtests scores were generated for 70 schoolboys and the data were then subjected to statistical analysis. A significant difference between English proficiency of the Grade 8 and Grade 12 boys was found. This indicates the importance of including an English proficiency test with the ImPACT battery when assessing such populations. No other significant differences were found between these age group samples. Although this requires further investigation, the comparison of the USA and SA percentiles suggests the use of local norms for this population. South African boys in this study consistently scored lower than the USA sample. Finally, it is recommended that symptom selfreports should be verbally investigated with each boy after testing, given indications of comprehension problems. In closing, limitations and future possible studies are discussed.

- Description: This evaluative case study investigates the use of a specific learning support materials (LSMs) package, Animal Awareness for World and Regional Education (AA WARE), in the natural sciences, intermediate phase. Schools with access to the resource were canvassed through questionnaires to assess overall use in relation to distribution via workshop versus hand delivery, class size, availability of alternate LSMs and lastly the level of exposure to the distributing organisation. Three case studies were undertaken at three different schools. Data was generated through observations and interviews with the teacher undertaking the lesson observed. The aim of the case studies was to gain greater insight into AAWARE in practice and the factors that facilitated the use of the resource by these teachers. The research indicates that while AAWARE has overcome some inhibitors of resource use, its potential within Outcomes-Based Education (OBE) and the Revised National Curriculum Statements (RNCS) has not been achieved so far, except in a few isolated cases. Factors enabling the use of the resource are its user-friendly design, availability in all three languages spoken by the majority of Western Cape learners and the integration with education policy. Workshops, although not necessary for the utilisation of AA WARE in part, could enhance the integrated nature of the resource and introduce teachers to the potential of using the resource as an entire unit as opposed to a collection of separate lesson plans. A relationship is seen between exposure to the distributing organisation, the personal interest in wildlife of the teacher and the use of AAWARE. Finally recommendations are provided to increase the use of AA WARE. It is suggested that the resource undergoes a more effective alignment to RNCS content (RNCS policy was not an issue) now that RNCS implementation is completed. Further workshops should be offered in the use of AA WARE. Lastly a long-term strategy should be developed to enthuse schools and teachers about the intentions, goals and appropriateness of the resource.

The evaluation of Phenrica sp.2 (Coleoptera: Chrysomelidae: Alticinae), as a possible biological control agent for Madeira vine, Anredera cordifolia (Ten.) Steenis in South Africa

- Description: Anredera cordifolia (Basellaceae), Madeira vine, is a perennial, semi- succulent climber native from Paraguay to southern Brazil and northern Argentina. It has a history of weediness and difficulty of control once established. In South Africa Madeira vine has a wide range and distribution with altitudes ranging from 10-1800m above sea level. Described as a transformer species, its sheer weight is capable of breaking branches off trees, causing the potential collapse of forest canopies. Chemical and mechanical control methods are expensive, labour intensive and may provide only temporary relief. A biological control programme was therefore initiated in 2003. Cf Phenrica sp. 2 (Coleoptera: Chrysomelidae: Alticinae), was field collected from A. cordifolia in Brazil, SSW of Cascavel in the Paraná Province during a survey in November 2003. Eggs are laid in groups of 16 with the average fertility rate being 89%. After going though three larval instars, the larvae pupate in the soil with the adults eclosing after a period of 17 days. The total developmental time for a generation from egg to egg ranges between 7-8 weeks. Biological traits that favour the flea beetle as a possible biological control agent include long-lived adults (up to 5 months) and multiple generations during the summer period. Both adults and larvae feed extensively on leaves and stems and although developmental rates will slow down during the winter period, no indication of a definite diapause was found under the prevailing laboratory conditions. After completing the larval no-choice trials with twenty-six plant species from 14 plant families Phenrica sp. 2 proved to be adequately host specific, as larval development was only supported by 3 Basellaceae species (including the control A. cordifolia) and one Portulacaceae species. All of these are introduced species in South Africa. The only indigenous Basella species could not be tested as it has a very marginal distribution, and because it’s inconspicuous nature, it is seldom seen or collected. Adult multi-choice trials were restricted to species that could sustain larval development to give some indication of the acceptability of these species for adult feeding and oviposition. Although adult feeding was initially concentrated on B. alba, the oviposition preference was clear-cut as females only oviposited on A. cordifolia. In order to quantify the impact of Phenrica sp. 2 on plant biomass and to assess the incidence and intensity of foliar damage, a pair of adults was confined to the host plant, for 2 generations, with different levels of larval densities. The results indicated that the host plant, due to both larval and adult feeding, suffered leaf losses of up to 55%. Anredera cordifolia was however still capable of enlarging the root mass despite suffering huge leaf losses. This would imply that A. cordifolia has an effective re-growth capacity and it will only be vulnerable to attack of the storage organs that enable re-growth, or to repeated attack of other plant parts through which reserves are exhausted. Unfortunately the period of exposure (24 days) was too short to prove that Phenrica sp. 2 impacts on the below ground dry mass, but should the plant be completely defoliated, as was observed in the field, the host plant would be forced to deplete stored resources. Phenrica sp.2 has shown to be very host specific and although A.cordifoia loses its leaves during the winter period in most provinces in South Africa, the adults are long-lived and should be able to survive the leafless periods. Further more the relatively short life cycle, high fecundity and 3 generations per year should theoretically insure a strong population build-up that would improve the chances of establishment in the field. All indications are that Phenrica sp. 2 is an agent well worth considering for the biological control of A. cordifolia.

- Description: The experience of verbal bullying at school may cause a female adolescent much distress. This distress can result in the adolescent experiencing life as traumatic and may influence her sense of well being negatively. Verbal bullying usually takes the form of name-calling, put-downs and insults. This can be very traumatic for adolescents and can lower their self-esteem, which may eventually lead to mental illness. The parents of adolescent learners often have the misconception that bullying is a normal part of a teenager’s life and are unaware of the distress it may cause the adolescent. The victimized adolescent should, therefore, be provided with support in order to avert the occurrence of mental illness. The goals of this study were to: • Explore and describe the experiences of adolescent girls regarding verbal bullying in secondary school settings. • Develop guidelines to assist mental health nursing specialists in helping adolescent girls to cope with bullying in secondary schools. The researcher used a qualitative, explorative, descriptive and contextual design with a phenomenological approach. The research population consisted of female learners in a secondary school setting. Purposive sampling was used in this study to identify participants. Data was collected by means of naïve sketches, one-to-one-interviews and field notes based on observations. Data was analyzed using Tesch’s method (in Creswell, 1994:190) of descriptive analysis. The identified themes were compared to available literature. The data collected from this study was used to develop guidelines to aid mental health nursing specialists to help adolescents to cope with verbal bullying.

- Description: The Department of Health in South Africa, as in many countries, has developed a policy guideline and recommendations for feeding of infants of HIV positive mothers. This is aimed at providing midwives with detailed and sound information about HIV and infant feeding practices based on current understanding of HIV and exclusive breastfeeding for the first six months of the infant’s life. The policy states that breastfeeding is a significant and preventable mode of HIV transmission to infants and there is an urgent need to educate, counsel and support women and families, so that they can make decisions about how best to feed infants in the context of HIV (http://www.doh.gov.za/aids/doc/feeding/html.2005-03-07). Speaking to midwives from the Provincial Hospitals in the Nelson Mandela Metropole, the researcher became aware of the midwives’ often-expressed unhappiness about the new policy from the Department of Health on exclusive breastfeeding. Midwives complained about the dilemma with which they are faced regarding infant feeding practices. They could not understand the advocacy of exclusive breastfeeding, when breastfeeding is recognised as one of the modes of Mother-to-Child Transmission (MTCT) of HIV. The aim of the study was to help, support and encourage midwives to implement the policy of exclusive breastfeeding. The objectives of the study were to: • Explore and describe the experiences and perceptions of midwives related to promoting exclusive breastfeeding in HIV positive first-time mothers. • Make recommendations to the Department of Health regarding the support and help that can be given to midwives to encourage their implementation of the exclusive breastfeeding policy. The researcher made use of a qualitative, phenomenological, descriptive, explorative and contextual design. Permission for conducting the research was iv obtained from relevant authorities, and participants were asked to sign a consent form before the researcher proceeded with the study. Collection of data was done by means of unstructured interviews using an audiotape recorder. Once data was saturated, the interviews were transcribed verbatim and analysed, using the steps described by Tesch’s (1990 in Creswell, 1994: 153) method of descriptive analysis. Field notes were also taken to record non-verbal communication during the interviews. In order to ensure trustworthiness of the study, the ethical principles of Guba’s model (in Krefting, 1991:215), namely truth-value, applicability, consistency and neutrality were used. The services of an independent coder were utilised and a consensus meeting was held between the researcher and the independent coder in order to discuss the identified themes. Prior to the consensus meeting, the independent coder was provided with interview transcripts and a protocol to guide the data analysis. Following the data analysis, a literature control was undertaken to highlight the similarities and differences found in the data analysis. Three themes with sub-themes were identified. The participants expressed positive views on the policy of exclusive breastfeeding in HIV positive first-time mothers. They were satisfied with the policy and viewed the policy of exclusive breastfeeding as an effective contribution to feeding options of babies born of HIV positive first-time mothers. However, the participants identified several factors hindering the effective implementation of the policy of exclusive breastfeeding in HIV positive first-time mothers. Factors identified were staffshortages, lack of cooperation among staff members regarding promotion of exclusive breastfeeding, lack of information regarding the CD4 count of patients on admission in the ward, cultural beliefs, lack of training among staff members and inadequate counseling facilities to ensure privacy and confidentiality for mothers. Participants also experienced a variety of emotions related to exclusive breastfeeding such as happiness, confidence, helplessness, frustration, worry and concern, stress and exhaustion. Based on the findings of the study, guidelines were developed and recommendations made concerning nursing practice, nursing education and nursing research.

However, the participants identified several factors hindering the effective implementation of the policy of exclusive breastfeeding in HIV positive first-time mothers. Factors identified were staffshortages, lack of cooperation among staff members regarding promotion of exclusive breastfeeding, lack of information regarding the CD4 count of patients on admission in the ward, cultural beliefs, lack of training among staff members and inadequate counseling facilities to ensure privacy and confidentiality for mothers. Participants also experienced a variety of emotions related to exclusive breastfeeding such as happiness, confidence, helplessness, frustration, worry and concern, stress and exhaustion. Based on the findings of the study, guidelines were developed and recommendations made concerning nursing practice, nursing education and nursing research.

- Description: Valvular disorders can be corrected by means of surgery, after which very comprehensive discharge planning should be implemented to prevent the occurrence of post-operative complications. Advances in medical technology and intellect instigate earlier discharge for patients after they have undergone valvular surgery. The aim of this research study is to establish the extent of discharge planning by nurses for patients who have undergone valvular surgery, so that practice guidelines in the form of an in-service educational framework can be compiled for nurses in the management of these patients post-operatively. Patients, many of whom are from rural areas, are discharged without an adequate referral system. There are, currently, no set guidelines or referral persons to direct these patients during their rehabilitation period. Based on the researcher’s personal observations, it is evident that many patients suffer from bacterial endocarditis or clotted valves due to poor post-surgery management. However, both of these conditions could be avoided if proper health education was given to these patients. The study will take the form of a quantitative, exploratory, descriptive and contextual survey. Data will be collected by means of a structured questionnaire that will be completed by the nurses working in the cardiac general ward and the cardiac clinic. Findings of the research study will be used to assist the researcher in developing an in-service educational framework for staff that are both nursing and preparing post valvular surgery patients for discharge. The goal is to prevent complications such as clot formation and endocarditis and to enable patients to deal effectively with their rehabilitation period.

- Description: Prior to the current constitutional dispensation, the development of South African administrative law was restricted by the doctrine of Parliamentary Sovereignty. Even in that comparatively 'hostile' environment, review for unreasonableness developed as an aspect of judicial review, and was applied as a check on the exercise of administrative power in certain circumstances. The principle of proportionality as an aspect of review for unreasonableness also developed during this period. With the advent of the new Constitutional dispensation, the framework within which administrative law in South Africa operates became one governed by Constitutional Supremacy. The Rights to Just Administrative Action, including a right to reasonable administrative action, were entrenched in the Constitution. Review for unreasonableness is an important aspect of administrative law in the present Constitutional dispensation as the mechanism for protecting the Constitutional right to reasonable administrative action. Proportionality is an important principle underlying the Bill of Rights as a whole, and it is an important aspect of the right to reasonable administrative action, and of review for unreasonableness. In early 2000, the Promotion of Administrative Justice Act No. 3 of 2000 ("the PAJA"), was passed by Parliament in fulfillment of the Constitutional requirement to pass legislation to give effect to the constitutional rights to Just Administrative Action. This thesis examines whether or not review for unreasonableness, and proportionality as an aspect of review for unreasonableness, have been meaningfully incorporated in the PAJA, and if they have not been, what potential remedies there might be. This is done by examining the basis of judicial review both before and under the current constitutional dispensation; defining unreasonableness, and proportionality; examining the content of the right to administrative action which is "justifiable in relation to the reasons given" in section 24(d) of the Interim Constitution and the right to reasonable administrative action in terms of section 33(1) of the Final Constitution; examining the application of review for unreasonableness and proportionality by the Courts both before and under the current constitutional dispensation; examining the content of judicial review incorporated in the PAJA and the drafting history of section 6(2) of the PAJA which relates to review for unreasonableness; drawing conclusions regarding whether or not review for unreasonableness and proportionality were meaningfully incorporated in the PAJA; and finally making recommendations with regard to review for unreasonableness and proportionality in light of the provisions of the PAJA.

- Description: This thesis investigates aspects of the diversity, abundance and biology of the fish species inhabiting Mnjoli Dam, an irrigation dam that is located in the rural lowveld region of Swaziland. Specific objectives for this thesis were: to determine the fish species present and select three principal species based on their abundance; to investigate the relative abundance and distribution of the three selected species; and to describe key population parameters, such as growth, maturity, reproductive seasonality and mortality. The three dominant species were selected on their fisheries potential. These were Marcusenius pongolensis, Oreochromis mossambicus and Schilbe intermedius. Marcusenius pongolensis was the most abundant species in terms of both catch per unit effort and mass. Catch rates were shown to vary according to habitat type. Age and growth parameters were obtained from sectioned otoliths. Marginal zone analysis showed that annulus formation occurred in winter for all three species. The maximum-recorded ages were 8, 6 and 8 for M. pongolensis, O. mossambicus and S. intermedius, respectively. Growth for the three species was best described by the three parameter von Bertalanffy growth model as Lt = 1.88.67(1- exp⁻¹·⁴⁸⁽t⁺°·⁶⁷⁾) mm FL for M. pongolensis; Lt = 226.83(1- exp⁻°·⁴⁽t⁺²·°²⁾) mm TL for O. mossambicus and Lt = 214.59(1- exp⁻°·⁶°⁽t⁺¹·²°⁾) mm FL for S. intermedius. Sexual maturity was estimated for male and female M. pongolensis at 134 mm FL and 119 mm FL, respectively. Oreochromis mossambicus matured at 239 mm TL and S. intermedius at 205 mm FL. Two spawning peaks for M. pongolensis and S. intermedius were observed, one at the onset of summer (November) and the second at the beginning of autumn (February-March). Oreochromis mossambicus also exhibited two spawning peaks, one in spring (September) and the second in autumn (February –March). Mean mortality rate (Z), estimated using catch curve analysis was 0.77 year⁻¹ for M. pongolensis, 0.49 year⁻¹ for O. mossambicus and 0.79 year⁻¹ for S. intermedius. Natural mortality was assumed to be equal to Z since there is no fishery activity at the dam. Size specific selectivity curves were developed for each species. Of all the mesh sizes used, the 44 mm mesh size net had the highest catch rates in terms of numbers for M. pongolensis and S. intermedius. The 75mm mesh caught the highest catch rates for O. mossambicus. . The 44mm and 75 mm meshes seem to be the most suitable mesh sizes for harvesting the candidate species. It is concluded that no commercial fishery should be established on the dam, yet a small subsistence fishery could be a possible option. Management options such as input controls, open and closed seasons and areas and minimum sizes are discussed.

- Description: From Introduction: The 'forensic aesthetic' presents the viewer with traces and debris - the residue that haunts sites of transgression, violence and death. In his book Scene of the Crime, art critic and curator Ralph Rugoff (1997:62) defines the forensic aesthetic as follows: "Inextricably linked to an unseen history, this type of art embodies a fractured relationship to time. Like a piece of evidence, its present appearance is haunted by an indeterminate past, which we confront in the alienated form of fossilized and fragmented remnants." Through its play on seemingly insignificant detail&, clues and traces, the forensic aesthetic suggests that meaning is dispersed, fragmentary and uncertain. According to Rugoff (1997:17), the forensic aesthetic "aims to engage the viewer in a process of mental reconstruction". It compels the viewer to adopt a 'forensic gaze' : to sift through broken narratives and fragments of information, reading the artwork as one might read a sample of evidence. Rugoff (1997:62) argues that: "[S]uch art insists that 'content is something that can't be seen' ... it requires that the viewer arrive at an interpretation by examining traces and marks and reading them as clues. In addition, it is marked by a strong sense of aftermath. ... Taken as a whole, this art puts us in a position akin to that of [the] forensic anthropologist or scientist, forcing us to speculatively piece together histories that remain largely invisible to the eye." One might argue that some of the earliest known examples of the forensic aesthetic in art presented themselves in the Renaissance period in the form of the pseudo-forensic anatomical drawings of Leonardo da Vinci. In his Studies of the Hand (fig. 1), for example, Da Vinci methodically represents the underlying structures of the human hand in a series of drawings that are scattered intermittently across the page. The remainder of the page is covered with hand-written notations. In this work, the artist approaches the human body with a scientific, almost forensic, gaze. Here the body is presented in fragments, rather than as a whole. According to Rugoff (1997:86&88), the forensic aesthetic addresses the body "not as a coherent whole but as a site of prior actions ... as a dispersed territory of clues and traces". When read in terms of the mode of the forensic aesthetic, Da Vinci's Studies of the Hand may be said to look at the human body as forensic object. In this way, this work may be said to speak of the manner in which the forensic gaze operates in the context of the artwork. Throughout the following essay, I discuss the various ways in which the forensic aesthetic manifests itself in art. I have necessarily been selective in the artworks that I have chosen for discussion, as this topic is very broad indeed. In Chapter One, I explore the tradition of the forensic aesthetic in art by way of a select number of artworks. This chapter focuses on investigating the way in which these works, whether consciously or unconsciously, speak of associations between violence and representation through the mode of the forensic aesthetic. The contents of Chapter Two concentrate on the work of South African artist Kathryn Smith. Smith's work may be said to possess a forensic quality, in that it references forensic practices and techniques. Her work has not been the topic of a lengthy monograph, but it has been considered in various exhibition catalogues, reviews and articles. For example, an essay by Colin Richards entitled 'Dead Certainties' (2004) investigates the forensic quality of Smith's imagery in terms of its play on notions of the trace. Similarly, an article by Maureen de Jager, entitled 'Evidence and Artifice' (2004), examines the manner in which Smith's work transgresses the boundaries between 'forensics and fantasy'. In her book, Through the Looking Glass (2004), Brenda Schmahmann addresses Smith's Still Life series (figs. 9, 10, 11) in relation to the issue of self-representation, exploring the relationship between the 'self' and the body as 'other'. Lastly, a review by James Sey, which was published in Art/South Africa (2004), considers Smith's work in terms of its aesthetic appeal, which serves as a framing device for the uncomfortable subject matter that informs the bulk of her imagery. My reading of Kathryn Smith's work departs from and expands on the available literature in that it focuses on the manner in which her images comment self-critically on the act of representation. I have chosen to focus on Smith's work in particular, as it uses the mode of the forensic aesthetic to speak of the field of artistic practice - a motif that runs throughout my own body of work as well. Moreover, Smith's work, like my own work, may be said to engage with the forensic aesthetic in a South African context. In Chapter Two, I compare a number of Smith's works to the artworks discussed in Chapter One, and examine the manner in which they speak of the links between art and crime. Chapter Three concentrates on outlining the ways in which my own work reads off the conventions of forensic investigation. In this chapter I discuss the manner in which my work, by way of a forensic approach, draws parallels between the medium of photography and the mechanisms of trauma. I focus on works that have been included in my Master's exhibition, Vigil (2005). The following essay is a study in representations of violence in art. In the course of this essay, I contextualize the forensic aesthetic as a mode of representation, as well as address the manner in which the forensic aesthetic seems to allow for, even facilitate, self-conscious reflection on the practices of representation itself.

- Description: The Palaeoproterozoic Earth experienced a global glacial event at 2400 Ma that occurred during the transitional period from anoxic to aerobic conditions in the atmosphere and oceans. The Transvaal Supergroup in the Griqualand West Basin, South Africa, hosts glacial deposits and associated major iron and manganese deposits that are apparently related to these global changes. The focus of this study is to assess the stratigraphy and geochemistry of the glaciogenic Makganyene Formation, in order to constrain its palaeoenvironmental settings. The Makganyene Formation forms the base of the Postmasburg Group and has been regarded as resting on an erosive regional unconformity throughout the Northern Cape Province. Systematic regional field observations and regional mapping carried out during this study demonstrate that this stratigraphic relationship is not universal. The Makganyene Formation is, in fact, conformable with underlying formations of the Koegas Subgroup in the deep southern Prieska basin and rests on an unconformity only on the shallow Ghaap platform to the north-east. The Makganyene Formation displays lateral facies changes that reflect the palaeogeography of the study area, and the advance and retreat of ice sheets/shelves. Geochemical investigations of glacial strata of the Makganyene Formation demonstrate that underlying banded iron formations of the Transvaal Supergroup acted as the main clastic source for the diamictite detritus. Geographic variations in bulk composition of the diamictites correlate well with field observations, and show that sorting processes were controlled largely by the morphology of the palaeobasin. Carbon isotope results emphasize the transitional nature of the Makganyene Formation in terms of the environmental conditions that resulted in widespread global glaciation in the Palaeoproterozoic. On the basis of the above geological evidence, it is proposed that the Transvaal Supergroup in the Northern Cape Province represents a continuous depositional event that lasted approximately 250 Ma and hence provides a unique opportunity for assessing the transitional changes experienced by the Palaeoproterozoic Earth.

The focus of this study is to assess the stratigraphy and geochemistry of the glaciogenic Makganyene Formation, in order to constrain its palaeoenvironmental settings. The Makganyene Formation forms the base of the Postmasburg Group and has been regarded as resting on an erosive regional unconformity throughout the Northern Cape Province. Systematic regional field observations and regional mapping carried out during this study demonstrate that this stratigraphic relationship is not universal. The Makganyene Formation is, in fact, conformable with underlying formations of the Koegas Subgroup in the deep southern Prieska basin and rests on an unconformity only on the shallow Ghaap platform to the north-east. The Makganyene Formation displays lateral facies changes that reflect the palaeogeography of the study area, and the advance and retreat of ice sheets/shelves. Geochemical investigations of glacial strata of the Makganyene Formation demonstrate that underlying banded iron formations of the Transvaal Supergroup acted as the main clastic source for the diamictite detritus. Geographic variations in bulk composition of the diamictites correlate well with field observations, and show that sorting processes were controlled largely by the morphology of the palaeobasin. Carbon isotope results emphasize the transitional nature of the Makganyene Formation in terms of the environmental conditions that resulted in widespread global glaciation in the Palaeoproterozoic. On the basis of the above geological evidence, it is proposed that the Transvaal Supergroup in the Northern Cape Province represents a continuous depositional event that lasted approximately 250 Ma and hence provides a unique opportunity for assessing the transitional changes experienced by the Palaeoproterozoic Earth.
